Ok so I have the sensor reading well with the code above and I have a sample of the seeduino datalogger that also seems to work but I cant seem to embed one code to the other and have it keep working. it just seems to put the poor little arduino into a coma after taking and writing one sample to the SD card.
Ill attach the datalogger code and hopefully some clever person out there can help.
this code works well on its own.

//Data logger Demonstration using Seeeduino Stalker v3.0. Logs Battery Voltage every 10 seconds to DATALOG.CSV file
//Use this demo code to implement your Datalogger functionality, add additional sensors.

//1.Solder P3 and P2 PCB jumper pads
//2.Compile and upload the sketch
//3.See if everything works fine using Serial Monitor.
//4.Remove all Serial port code, recompile the sketch and upload.
// This reduces power consumption during battery mode.
